Motion:
* Definition: Motion is the change in position of an object over time. It describes the movement itself, not how fast or slow it is happening.
* Examples: A car driving down the street, a ball rolling across the floor, a leaf falling from a tree.
Speed:
* Definition: Speed is a measure of how fast an object is moving. It quantifies the rate of change in position over time.
* Calculation: Speed = Distance / Time
* Examples: A car traveling at 60 miles per hour, a sprinter running at 10 meters per second.
How they relate:
* Speed describes motion: You need to know the motion (that an object is moving) to talk about its speed.
* Motion is not always described by speed alone: Motion can be described by other factors like direction (velocity) or acceleration (change in speed over time).
In summary: Motion is the act of moving, while speed is a numerical value that tells you how quickly the motion is happening.
